When a visitor signs up for an account on your website, a notification with the following text is sent to their email address:
Thank you for registering on [Company name]!
Login to your account: https://mydomain.com/login/
If you want to change this default text, copy file wa-system/webasyst/templates/mail/Signup.html and save the copy to wa-config/apps/webasyst/mail/Signup.html.
Edit text and Smarty code in the copied file and save the changes.
Done! The updated text will from now on be sent to website visitors on signup.
